Play Online Slots at Home

The main advantage an online casino can give you is the possibility to play your favourite games from the comfort of your home. Living in this modern world has changed how things work, including how we entertain ourselves. There are minimum chances someone will run to the closest brick-and-mortar casino to enjoy a slot game since the best online slot sites are just one click away.

Play Online Slots at Home

The digital elements allow you to get comfortable on your couch, log in to your account and start playing whenever you want. You can also play on the go if you’re more active since providers have developed numerous mobile slot sites. In other words, online slot sites have become increasingly popular lately, providing everyone with the comfort they need.

There is, though, a key point many players overlook when choosing new slot sites to try out. Many best slot sites have higher RTP percentages than most casinos, offering you the greatest deal there is. A good RTP will work in your favour giving you more chances of winning significant amounts.

To get a more precise idea, most land-based games have an RTP of around 90%, but it’s not unusual that the percentage goes down to 80%. On the contrary, slot websites worldwide offer online games with a great range of RTP, somewhere between 93 and 99%.

Along with the great RTP, many online independent slot sites offer free slots to test the games and their newly launched platform. It is a common method that attracts new users to the platform making their first gambling experience exciting and fun.

SlotsCalendar Advice: We recommend that you always test the games for free in demo mode before deciding whether or not to try them for real money. This way, you will know what to expect, how the game works, if winning is possible and, overall, whether you enjoy it. And you won’t waste your funds on a dud. 

Slots Bonuses Variety

Before signing up for a new gambling site, it’s important to know what to expect, including slots bonuses. There is an excellent category for new players from which they can choose the best slot sites no deposit bonus.

Best bonus slots offers include:

  • Slots welcome bonuses that you get as soon as you sign up to a gambling platform;
  • No deposit bonuses where you get some cash to play with and try out a casino risk-free.
  • Monthly bonuses & promotions as a loyalty reward;
  • High roller bonuses for those who make regular large deposits;
  • Game-specific bonuses that encourage you to try the newest games.

SlotsCalendar Advice: Take time to understand under what conditions you may claim your bonus offer. You might find out that the bonus is only available on a specific game that you don’t particularly enjoy.

9 Tips for Choosing the Best Slot Sites

Choosing the best slot gambling sites can be pretty challenging when the market offers so many options. Here, at SlotsCalendar we put you first so that we offer valuable information to make your gambling experience fantastic.

9 Tips for Choosing the Best Slot Sites

We know that selecting trustworthy websites can be confusing and time-consuming; thus our expert reviewers gathered these tips to help you find the best slot sites for winning.

1. Check the Casino’s Gaming License

A lot of UK casinos have a gaming licence issued by UKGC. When looking to play at these casinos you’ll know that they have to respect the strictest licensing conditions worldwide. As you visit the gambling platform make sure to check the following elements:

  • UKGC logo;
  • The Casino’s licence status;
  • The casino’s licence number.

2. Research the Slot Game Providers

Famous providers can indicate if you are on a good gambling website. The most widely available providers are NetEnt, Microgaming, Playtech, Play’n Go, and Scientific Games.

However, many fresh suppliers produce real hidden gems, so you just need to be careful when checking them out. 

3. Read Reviews of the Good Slot Sites

Our team created a strong list of casino reviews for your peace of mind. Our lists include ratings, features, and also player experience along with in-depth testing, including real money deposits and withdrawals. This way our experts could carefully cover all aspects of the review. 

4. Try Sites with Slots bonus

You may find different bonus offers on online casinos. You have plenty of options to choose from, but make sure the bonus works for you and matches your gambling style. Always pay attention to the fine print (wagering requirements, max cashout cap, max bet, time limits, games available etc) of slot bonuses.

5. Play Easily on the Best Mobile Sites

Most gambling games are 100% optimised for all smart devices, including mobile phones and tablets. Excellent mobile gambling websites have a great variety of games that function flawlessly on your prefered device. Along with the games you also get multiple payment options tailored for mobile phones.

6. Know Your Favourite Gaming Style

Get a clear understanding of the style of games you prefer and which studio produces them. When knowing exactly what games work best for you it’ll get easier to choose a place to play. The next step is to figure out whether you’re interested in penny slots or wish to be a high roller and bet big. There are plenty of options for each side you pick. 

7. Look for a Wide Variety of Games

The number and range of games will always highlight the diversification a gambling website has to offer. While having access to classic casino table games, video poker, live dealer games, and bingo games would be a nice plus, it’s more important to have all types of slots – classic fruit slots, video slots, 3D slot machines, megaways slot games etc. 

8. Check That You Can Withdraw Your Earnings Fast & Easy

The ways of funding your account and withdrawing your cash at an online casino have to be multiple. Most websites feature safe and secure payment methods that also function very quickly and efficiently. 

9. Customer Support

When looking for the best gambling platform most players overlook the website’s support feature. Whether it is a live chat or a non-stop line, every reputable platform has to offer this service. 

You’ll probably need to query a promotion or might need help withdrawing your earnings, the thing is that you’ll need support. A reliable customer service team that functions impeccably is essential to a site’s reliability and success.

There should be diverse ways you may use to get in touch with a team in case of possible questions, issues, or queries. These ways include:

  • Live Chat – the fastest way to get in touch, through text.
  • Telephone – for those who like to solve problems verbally.
  • Online Services – WhatsApp, Skype, or Zoom
  • Email – this is a must in any type of business
  • Social Media – Active Facebook, Instagram, or Twitter accounts
  • FAQs – website’s help section to cover most queries
  • Callback – some may call you back whenever is convenient for you.

Slots Sites UK vs Non UK Slot Sites

There are already hundreds of licensed gambling platforms on the UK market, yet new ones are opening their digital doors for players every month. Licensed online casinos offer higher security while the UKGC is working for your rights.

However, some players are still looking for the huge bonuses and the gamification part of casinos. As the strict rules of UKGC have limited this possibility for many licensed casinos, multiple players look for non UK slot websites to fill this market gap.

If you have already played many online casino games throughout the years, you’ve most likely played on some non-UK casinos. Statistics show that many casinos operating online in the UK are based offshore.

When talking about non-UK casinos, you need to know the difference between casinos not based in the United Kingdom and those with a non-UK license. To understand the difference, have a look at this table:

  • Usually based off-shore due to tax reasons.
  • A large part of online operating casinos in the United Kingdom are based outside the area.
  • Normally own a UKGC license.
  • Is tax-free as long as they own a UKGC license.
  • They are licensed under another jurisdiction and not the UKGC.
  • More freedom to act outside the UKGC’s guidelines and regulations.
  • These operators are not on GamStop, meaning less security.
  • Offer bigger bonus offers than a UK-licensed casino.


SlotsCalendar Advice: Our top priority is your protection, that’s why we review all our casinos and check their license for you. Still, you should quickly scan every casino you wish to try for a license number. You should be able to easily spot it in the footer of each casino site.

Enjoy the Best Online Slot Sites by Category

Nothing compares to a well-organised site where you may find what you need at your fingertips. In order to offer you a hassle-free experience, here are your favourite slot games divided into different categories.

Enjoy the Best Online Slot Sites by Category

New Slot Sites

When looking for new casino sites, make sure to enjoy the latest technology trends that offer a stellar experience. These ones usually come with the best promotions and no deposit offers because they are trying to make an impression on players, get new members to check them out and make a name for themselves in this gambling industry.

Mobile Slot Sites

Many online casinos are looking to upgrade their websites by making them mobile-friendly. That is why some gambling platforms offer specific bonus features available only on mobile. See how mobile casino bonuses can increase your earnings.

Best Slot Sites No Wagering

Probably the best sites provide you with no wagering bonus slots, meaning that everything you win is yours to keep and withdraw immediately. Check our list of no-wagering casinos and give your best shot!

5 Deposit Slot Sites

The casino industry is constantly updating to meet the expectation of new generations of players. Aiming to provide the best user experience, the gambling market created the minimum deposit casinos, which offer the opportunity of playing different games with a low budget.

Payment Methods

As e-wallets have become quite popular in the last few years, online gambling platforms have upgraded their payment methods by adding more options to deposit and withdraw your money.

Many online casinos, if not all, now offer different forms of payment, including debit cards (Visa, Mastercard) and online options (PayPal, Apple Pay, Skrill, or Neteller). According to the UK Gambling Commission, credit cards are no longer allowed for gambling activities, so make sure you have the necessary payment method before making a deposit.

Every player has their preferred payment method when playing online games. Yet, not all casinos allow so many options. That’s why it’s best to check what is accepted for players who like paying online. On the market, you’ll find a lot of PayPal slot sites, and some slot sites that accept PaysafeCard, but not as many casinos that use Skrill or Neteller.

SlotsCalendar Advice: Check if any fees are applied when using online payment methods. It may cost you money to use these options, so sometimes it is better to stick to a bank transfer or debit card.

Online Slots Gambling Sites & Responsible Gaming

Gambling is always fun and sometimes risky, and that’s why it’s important to set your boundaries.

When playing online gambling games, it’s important to understand the mathematics behind them and stay in control. Many casinos create special sections on their website so that all visitors are aware of potential risks in regard to gambling. They create a guide to help them spot the warning signs of any potential gambling addiction.

Most slot and casino sites are required to include different responsible gaming options including:

  • Deposit limits which give you control over your spending. Once you set a limit you won’t be able to deposit more.
  • Take-a-break option which will give you time to step back from gambling if you feel you need to. It can take one, two, or seven days, one month, or six weeks. It all depends on you.
  • Self-exclusion will help you stay inactive for specific time periods you set. This option won’t let you make another deposit.
  • Help-Centre: In case you need extra support for possible gambling addiction, you can always contact professionals through a help centre.

SlotsCalendar Advice: Before starting to play, set a budget and stick to it. Gambling should bring you joy and excitement rather than frustration and anxiety.
